Kale is the hipster vegetable enjoying a moment in the superfood sun, so no one thought it would hook up with dowdy old brussels sprouts.
Yet the resulting love child, named 'kalettes' are winning friends around the world with their nutty, sweet flavour, and they're being grown and sold in Australia.
They take after mum with curly, green kale-like leaves but you can't mistake dad's tightly packed shape.
Kalettes were invented by U.K. farming company Tozer Seeds in 1995 and were not genetically modified beyond the age-old method of crossing two similar plants.
In this case, kale and brussels sprouts are both of the brassica genus and one pollinated the other, over multiple generations until a plant was created with the right mix of kale's leaves and brussels sprouts' shape.
Adelaide Hills family farming business Samwell and Sons began growing kalettes last year for Coles.
Managing director Scott Samwell said kalettes had a stellar run last season so they upped their production.
"In a single day we sold the entire volume of Kalettes we were hoping to sell in the first week, so this year we've planted six times more," Samwell said.
"For more than 50 years my family has been growing Brussels sprouts in the Adelaide Hills and I wanted to bring something to the business that was different and this definitely has added a new dimension to our business."
